Typing accentuated characters in Maemo is not the easiest nor the fastest action to perform. This is certainly not a huge issue for english speakers, but it may be for others.
Simple example : we french people love to put accents everywhere, because it's sooo much fun! :p
If you want to type the word "été" (french for summer), you have to type the following sequence :
Fn + Sym + accent + e + t + Fn + Sym + accent + e
That's a lot of keystrokes for a 3-letter word!
As many other languages make use of accentuated characters (i.e. German), improvement in this area would be much welcomed :)
